The more months payed for upfront, the cheaper the cost per month. E-liquid subscriptions range in price form $29.99 paid monthly, $86.97 paid every three months or $167.94 paid every six months. All three plans include shipping in the price.
I would guess that this is in keeping with Aldi's business model of only carrying the highest volume items in their store. Lullabies are priced at $4.99 per pack. For price comparison I will use the Size 3 which has 36 diapers per pack, making the cost 13.8 cents per diaper. Here are the current costs per diaper and equivalent price per pack of some other popular diapers based on online pricing. Target Up and Up 15.5 cents per diaper or $5.58 per pack. Pampers Cruisers 27.3 cents per diaper or $9.83 per pack. Huggies Snug and Dry 22.3 cents per diaper or $8.03 per pack.
